Oil Separator Small Vacuum Hose

I purchased a CCV kit for my 2001 BMW 525i. Installing it, for a moderately experienced DIYer, was a bit frustrating. I was able to find 3 video segments on Youtube that did a good job of providing step by step (look up M54 Crankcase ventilation). I have 2 issues for the forum - one a question and the other a comment/suggestion.

The new oil separator(OS) has a small port that was unplugged upon receiving it. Official BMW records say that port is "required" for my model year car. My old OS is not have it so I am thinking just plug it up. What should I do and if needed where does it bloody connect to?

In order to connect the breather hose (valve cover to OS) I used a heat gun to soften the OS side due to it being very stiff. I actually broke the first OS trying to connect this one. (urrrrgggg!) Sometimes these aftermarket kits require a little finagling right?

Responses appreciated. Here is what I am talking about.
